Parts for your 2006 Mitsubishi Pajero-Ignition leads

2006 Mitsubishi Pajero ignition leads — what’s actually fitted

For the 2006 Mitsubishi Pajero sold in Australia and New Zealand, traditional ignition leads (spark plug leads) aren’t used on the factory petrol or diesel engines. Instead, the 3.8‑litre V6 petrol (6G75) runs individual coil‑on‑plug (COP) units mounted directly on each spark plug, and the 3.2‑litre Di‑D diesel (4M41) doesn’t use spark ignition at all. This layout is confirmed by Mitsubishi’s Workshop Manual for the 2006 Pajero (Ignition System section) and Mitsubishi’s ASA/CAPS electronic parts catalogue, both of which show six plug‑top coils on the V6 and no high‑tension leads, and no ignition components for the diesel beyond glow plugs.

Why no ignition leads? With COP, each cylinder gets its own coil perched right on the plug. That shortens the high‑voltage path, improves spark energy and timing accuracy, and removes the usual wear points found in leads (cracked insulation, arcing, moisture ingress). It’s tidier under the bonnet and typically more reliable over the long haul. On the diesel, there’s simply no spark system to begin with—combustion is compression‑ignited, so there are no coils, plugs leads or distributors to worry about.

What should Pajero owners service instead? For petrol models, the key items are spark plugs, the coil boots, and the coils themselves. Many drivability complaints blamed on “leads” on older cars will, on a 2006 Pajero, trace back to aged plugs, a torn coil boot, or an individual coil starting to break down—often after heat cycling or if oil seeps into the plug tubes from a rocker cover gasket.

• Replace spark plugs at the recommended interval, using the correct heat range and gap.
• Inspect coil boots for carbon tracking, splits or hardening, replace any suspect boots.
• If there’s a misfire, scan for cylinder‑specific codes (e.g., P0302), then swap the suspect coil to another cylinder to confirm the fault.
• Check for oil in plug tubes, fix rocker cover/tube seals if needed to protect coils and boots.
• Use a dab of dielectric grease inside the boot to aid sealing and future removal.

It’s worth noting some earlier‑generation Pajeros used conventional leads, which is why a few generic parts listings still show “ignition leads” for a 2006 model. For AU/NZ‑spec 2006 vehicles—NP late and NS—those listings don’t apply unless the engine has been retrofitted or swapped.

Popular questions about 2006 Mitsubishi Pajero ignition leads

Does a 2006 Mitsubishi Pajero have ignition leads?
No. The 2006 petrol V6 uses six coil‑on‑plug units and the diesel uses compression ignition, so there are no traditional high‑tension leads. If you see leads listed online, they’re usually for earlier generations or universal kits that don’t suit this model.

What should be serviced instead of ignition leads on the V6?
Focus on spark plugs, coil boots and the individual coils. Keep an eye out for oil in the plug tubes from rocker cover seal leaks, as that can damage boots and cause misfires. Regular plug changes and a quick coil/boot inspection go a long way.

How do you diagnose a misfire without leads?
Scan for fault codes to pinpoint the cylinder, then swap that coil to another cylinder to see if the misfire follows. Inspect the boot for tracking, check plug condition and gap, and address any oil contamination around the plug tubes.
